Abstract:
:Double immunofluorescence studies for terminal deoxynucleotidyl transferase (TdT) and leucocyte surface membrane antigens have been used to characterize the small subpopulation of TdT-positive cells in human peripheral blood. The predominant antigens demonstrated were those coded for by the major histocompatibility complex, namely HLA-A,B and Ia-like antigens. A small proportion of TdT+ cells expressed antigens restricted to B lymphocytes and their precursors (BA-1+ CALLA+). In contrast, antigens associated with T-lymphocyte differentiation were not detected using a panel of T-cell-specific monoclonal antibodies. These results preclude the possibility that circulating TdT+ cells are immature cortical thymocytes that have "leaked" into the bloodstream. Although bone marrow-derived prothymocytes, which have not yet acquired T-cell lineage markers, may be included amongst this subset, the expression of B-cell related antigens by some TdT+ cells indicates the likely existence of lineage heterogeneity amongst this population of lymphoid cells. The relevance of these findings to the monitoring of human acute lymphoblastic leukaemia is discussed.
